Previous studies have revealed the significance of Helicobacter pylori (H. pylori) infection as a risk factor of gastric cancer. Cytotoxin-associated gene A (cagA) positivity has been demonstrated to determine the clinical outcome of H. pylori infection in the presence of SHP-2 (src homology 2 domain-containing protein tyrosine phosphatase-2). This study aimed to examine the formerly reported association of G/A PTPN11 (protein-tyrosine phosphatase, nonreceptor-type 11) polymorphism (rs2301756) with gastric atrophy, as well as the association with gastric cancer in a Japanese population using a large sample size.
